The song is by АНЖ (ANJ), described as "Gogol Bordello meets Megadeth", and the vid is part of the surely underappreciated computer game Stalin Vs.

(The trailer, in case you're curious, features an animated Stalin dancing to Snap!'s Rhythm is a Dancer.)
If you're wondering what the hell the lyrics are, the video's creator, Tom Stern, presented his handywork nine months ago at Vimeo and he posted the lyrics in comment #90 (near the bottom of the first page).
